Does anybody have highres photos of the area around the connector for the screen?
Or experience with this kind of problem?
While replacing the screen of my SGP521, I attached the cable the wrong way around and some stuff got burned.
Attached a photo of what it looks for me.
The blue circle shows the broken/missing/burned thing.
I found the following image in an ebay auction.
In case anybody runs into this.
It looks like the burned area is connected to pins 6 and 7 on the connector and connected to ground through two capacitors.
Hey! We're you able to solve this?
My dad ran into the same problem and burned out capacitor...

hey everybody!
just noticed that my lower microphone is covered by sth from inside the case. it looks similar to the attached photo, but my microphone is even more covered from this white thing inside as seen on the photo. the black hole seems so be nearly outside. the other micro on top is centered right.
is anybody of you experiencing the same?
could be relevant for my acoustics probs.
thanks!
no ones able to check his own s2 and tell me if he look at the same thing!?

I have replaced a lcd display a some time ago. The replacement LCD was working fine, but after a few months the replacement lcd display is showing a strange and wrong color gradient. It looks like old 16bit colors...
My hardware related question, could this problem be cable or lcd or mainboard related?
Yikes. I'd suspect a physical issue with the display. What do you see when you connect to an external HDMI screen?

When the hdmi cable is plugged between tablet and my tv, there is nothing wrong with output.
Today i have replaced also the flex cable, that did not help either.
Could the problem on lcd dispay be fixed? :'(

I'm speculating on the damage being with the LCD. I'm an IT professional (20+ years), so I do have a bit of experience here. One thing that's concerning is how the screen is separated, vertically, into the four bands. LCD screens are ridiculously delicate. I know from experience, having broken mine when replacing the digitizer glass.
LCD screens are typically very difficult/impossible to repair. It's cheaper/easier to just replace. I know this sort of sucks. Perhaps you can buy a replacement from a vendor that has a decent return policy. I'd use rubber gloves to handle the replacment (no fingerprints). Temporarily connect it. Problem gone? Then it was your LCD. Problem persist? (unlikely). Repack and return the replacement screen.
Good luck.

OK I have ordered a new lcd display, lets hope this will solve my problem.
Thanks everyone for your reactions.
I have disassembled this mobile phone because I had a problem with the digitizer in one small area of the screen. I replaced the digitizer, but now I am not sure about how to connect the LCD… I should have taken pictures :-s.
Some pictures of the problem:
The connector is the zone with the red box, I do not remember if it goes on the grey plastic (it is not connected in this picture because it is difficult to keep it in).
Or under the grey plastic:
It is connected in this picture, but when I switch the phone on I can only hear the booting sound, no image on the screen…
Can any of you open your phone (just 4 screws) and take a picture of the LCD connector?? I cannot find any disassembly guide on the internet for this particular model…
Thank you very much in advance!
Regards!
PS: I cannot post pictures yet because I do not have enough messages on this forum... If you are interested I can send you this links in a pm...
EDIT: SOLVED!!
I finally solved it :victory:, the connector goes under the grey plastic
Regards

Hi All
Just started to buy up some old (spare or repair) I9100 phones with the hope of getting at least one which would work fully. I now have the final product but still no working screen! The screen I have looks perfect but shows nothing, I've tried the following:
Shine torch on screen to see if the LCD is damaged (nothing)
putting the screen on a second S2 (nothing, but it is not known if the second one actually works beyond making the right noises on start up)
Cleaned off all the connectors
I really don't want to take the screen off the frame so I wanted to know if anyone knows about testing/fault finding on the LCD with a multimeter type set up, like maybe a pin out or test points. Failing this I'm thinking of selling it all back on, so with that in mind does anyone have any advice on the IMEI and what to advertise.
oh and I've got some reasonable images of the LCD connector and some of the resistors which can be seen through the viewing ports in the frame for possible continuity tests.
Thanks in advance.
Hi all,
I broke my screen and ordered a new one (without frame). Replacing it was easy (after waiting for it for more than a month... thanks COVID-19), except that I was dumb enough to miss it was using a ZIF connector, and forced-push the cable in (shame on me).
It broke some pins, at first I didn't even notice but when looking at some stuff I took a picture off, it clearly appeared some colors were... unusual (pink instead of green ). So I double checked and indeed, pins had been damaged.
Anyway, to my question: do you know by any chance where I could find a screen frame (which comes with the fcc cable the zif connector is soldered on)? I only found frames with the screen attached and of course I don't need another new screen...
I checked ebay, but the ones I found don't look at all like the original.
I'd also be interested by the cable alone, but it would be way harder to put back in place I guess (as it's also holding front sensors).
If someone has a dead Mi Mix 3, it could also be helpful...
Thanks!
EDIT: nevermind, Amaan at Cellspare.com did an awesome job finding the flex cable and adding it to their listing when I asked him for help! Everything's getting better now
